WlNDMILL-COUPLING.

SPECIFICATION forming part of Letters Patent N 0. 686,848, datedNovember 19, 1901.

Application filed March 28, 1901. $erial No. 53,320. (No model.)

T0 all whom it may concern.-

Be it known that I, DWIGHT M. HATCH, a citizen of the United States,residing atEast Delavan, in the county of Walworth and State ofWisconsin, have invented a new and useful Windmill-Coupling, of whichthe following is a specification.

The invention relates to improvements in windmill-couplings.

The object of the present invention is to improve the construction ofthe means employed for coupling a pump-rod to a windmill and to providea simple, inexpensive, and efficient device adapted to be readilyapplied to a windmill and capable of enabling the pump-rod to be readilysecured to and disconnected from the same.

A further object of the invention is to provide a device of thischaracter which will be adapted for use in connection with cushionedpump-rods and which will be capable of yielding to the expansion andcompression of the cushioning device.

The invention consists in the construction and novel combination andarrangement of parts hereinafter fully described, illustrated in theaccompanying drawings, and pointed out in the claimshereto appended.

In the drawings, Figure 1 is a vertical sectional view of awindmill-couplingconstructed in accordance with this invention, theupper and lower sections of the pump-rod or plunger-rod being coupled.Fig. 2 is a similar view, the parts being uncoupled. Fig. 3 is a sideelevation, the parts being arranged as shown in Fig. 2.

Like numerals of reference designate corresponding parts in all thefigures of the drawlngs.

1 and 2 designate upper and lower sections of a plunger orpump-rod, theupper section 1 being designed to be connected in the usual manner to awindmill and the lower section 2 being connected with the pumpmechanism. The upper section carries a frame 3, receiving a spring 4,which is interposed between the bottom of the frame and an uppercrosshead 5, and the latter is connected by rods 6 to the lowercross-head 7. The frame, the spring, and the cross-heads form acushioning device of the ordinary construction, and when the lowercross-head is secured to the lower section of the pump-rod or plungerthe two sections of the same are yieldingly connected and are cushioned.

Thelower cross-head, which is arranged beneath the frame, is providedwith a perfora tion 8 for the reception of a pin or key 9-, which isadapted to pass through a perforation of the lower section of thepump-rod or plunger, as clearly illustrated in Fig. 1 of the device 9 isout of engagement, asillustrated' in Fig. 2 of the accompanyingdrawings. The bottom of the frame is also provided with an opening whichregisters with the openings of the upper and lower cross-heads toprovide a way, for the lower section of the pump-rod.

The pin or locking device 9, which is provided at its outer end with aneye 10, is retained in engagement with the lower section of the pump-rodby a spring 11, bolted or otherwise secured at its upper end 12 to oneside of the frame and having its lower end or portion 13 reduced andarranged in the eye 10 of the locking device 9. The lower end of thespring 11 is perforated for the reception of a key 14, which forms astop or bearing for a coiled spring 15, which is arranged on the reducedportion of the spring 11 and which is interposed between the stop andthe locking device or pin 9. By this construction a yielding connectionbetween the locking device 9 and the longitudinal spring 11 is providedto yield to the action of the cushion formed by the main coiled spring 4and to prevent the spring or the locking device from being strained bythe expansion or compression of the main cushioning-spring.

The longitudinal spring 11 is provided between its ends with an eye 16,receiving a pivot 17 of a cam-leverlS, having a bifurcated head 19, inwhich is arranged the pivot 17. The bifurcated head receives thelongitudinal spring 11 and projects outward from the body portion of thelever and is provided with curved edges 20 and with straight outer edges21. The curved edges are adapted to abut against the adjacent side ofthe frame to permit the longitudinal spring to be readily forcedoutward, and the square edges are adapted to fit against the frame tohold the spring in its flexed position, as illustrated in Fig. 2 of theaccompanying drawings. The transversely-disposed pin or locking deviceis adapted to be readily drawn outward when the lever is swung upward,and it is held in engagement with the lower section of the pump-rod andcarried to such position when the lever is swung downward by thelongitudinal spring 11.

It will be seen that the device for locking the pump-rod section 2 tothe upper section 1 is exceedingly simple and inexpensive inconstruction, that it is easily operated, and that it is adapted toyield to the expansion and compression of the cushion.

What I claim is- 1. In a device of the class described, the combinationwith the upper and lower sections of a pump-rod or plunger, of alockingpin for connecting the sections, a spring connected with thelocking-pin and adapted to hold the same in its engaging position, and abifurcated cam-lever straddling the spring and pivotally mounted on andcarried by the same, substantially as described.

2. In a device of the class described, the combination with the upperand lower sections of a pump-rod or plunger, and a cushion, of alocking-pin for connecting the said sections, aspring slidably connectedwith and capable of longitudinal movement independently of thelocking-pin to permit the latter to move with the cushion, and means forhold in g the spring to retain the locking-pin out of engagement,substantially as described.

3. In a device of the class described, the combination with the upperand lower sections of a pump-rod or plunger, and a cush ion, of alocking-pin having an eye or opening, a longitudinal spring passingthrough the eye or opening and adapted to hold the locking-pin in itsengaging position, a coiled spring disposed von the longitudinal springand engaging the same and the locking-pin, and a lever connected withand adapted to hold the longitudinal spring in a flexed position,substantially as described.

In testimony that I claim the foregoing as my own I have hereto aflixedmy signature in the presence of two witnesses.
